2005 E320CDI - Cleaning the EGR Valve, what's needed?
As soon as it gets somewhat warm here, I need to pull my EGR valve and clean it. The car drive perfect back from Atlanta when I bought it, but I noticed it's not fully warming up. Just getting to 50C on the road. So, going to replace the thermostat. But having some lurching issues at part throttle where the car just lunges back and forth under part throttle at low RPMS, and the RPMs bounce up and down also during that period. It sounds like EGR from what I've been reading. Anyway, if I pull the EGR to clean it, A) What should I soak it in, and how should it be cleaned? and B) Will I need to order some sort of gasket to reinstall the valve?
Thanks!

Coolant and bolts
The trick is the coolant line is very hard to get off. Also getting to the bolts is very difficult. And it is basically a big box with two holes on each end. So the only way to really clean it is to soak it. then you would probably have to bake it to get the moisture out. And there is basically a coolant radiator on the inside of the chamber.
The valve is of course a nominal part. What would it take to just block it off the whole chamber not just the valve. What would it take to remove the whole chamber? And eleminate the whole EGR cooler and valve? |

EGR
The actual EGR switch is right on top. It comes out relatively easily. It is sealed in with a rubber gasket and just has to be wiggled out of its hole. But even before you do that just take the plastic cover off the end with a small screwdriver. And you will see the arm that pushes the valve up and down. Push on it with you finger to see if it goes up and down. It should. You can take the whole thing out if you like but that will never be the problem it is the EGR cooler that gets clogged up with soot. That is much harder to take off. Much harder to clean.
Sorry for the long response time. |
